Data are shown for the total number of collaterals obtained from all study hearts. Collateral density was highest in the subendocardium of the left ventricular free wall and mid-myocardium of the septum. Abbreviations: Endo, endocardial layer; Epi, epicardial layer; LVFW, left ventricular free wall; Mid, mid-myocardial layer; RVW, right ventricular wall; and SEP, septum. *P < 0.05 and **P < 0.01, Student's t test compared with the endocardial layer of the LVFW. No significant differences exist between the other groups.
